``` Here's what's new in this build: **🎯 Ghost Well Mechanic** — Your cursor is always an active gravity well, chasing your mouse with spring physics lag. Move fast and the ball gets flung past it — you have to lead it, not follow it. **🖱️ Hold to Plant** — Hold the mouse button and wells auto-plant every 0.38s as you drag. Wells have a lifetime bar and expire, keeping things dynamic. **🕳️ Black Holes** — Spinning accretion disk, red event horizon, inward-pulling gravity. Touch the center = instant death. **🔴 Patrol Orbs** — Orbital and linear sentinels with spiky glows. Touch = destroyed. **🌀 Rotating Barriers** — Spinning line obstacles with proper circle-vs-segment collision. **📦 Moving Walls** — Oscillate on sine waves with pulsing highlight glow. **⚡ Speed Strips** — Animated arrow currents that blast the ball directionally. **💥 Repulsor Mines** — Outward-pulsing hexagon mines that violently push the ball away. **5 Themed Worlds, 20 Unique Levels** — Deep Space → Nebula Drift → Ice World → Solar System → Void Realm, each with unique background, planets, wall colors, and increasing spring lag on the ghost well.
